Pietenpol Sky Scout - Background
The Pietenpol Sky Scout UM was designed as a lower-cost, follow-up to the enormously popular Air
Camper, Bernie Pietenpol’s first homebuilt design. A lower cost (at the time) Ford Model T engine was
used, rather than the more current Ford Model A engine of the time. The aircraft was redesigned to use
the heavier, lower-powered engine by making it to a single-seat aircraft. The new location for the pilot
required a section called a "flop" to be installed in the wing. Essentially, a section of the wing was hinged
up to allow the pilot to stand up when getting into and out of the aircraft.
The original drawings were published in the 1933 issue of Mechanix Illustrated Magazine. Designed to
be built out of spruce, plywood and fabric, by the aviation enthusiast, many versions of this popular
aircraft were built, and are still being built today.
Relive the excitement of the golden age of aviation with our ultra-micro version of this famous aircraft.
The Stevens AeroModel kit offers a modern kit design that builds trouble-free and quickly, thanks to
modern design processes, pioneered by Stevens AeroModel.

General Assembly Instructions
Thank you for purchasing the Pietenpol Sky Scout UM from Stevens AeroModel.
This model has been developed and manufactured using state-of-the-art CAD/CAM systems. Our kits
feature a unique interlocking construction process, that when compared to traditional building methods,
saves countless hours of measuring, cutting, sanding, and fitting. We are certain that you’ll find our kit to
offer a truly exceptional build experience.
As this kit is recommended for the novice model builder and pilot, we invite beginners who have
purchased this kit to seek the help of an experienced builder and pilot. If you run across a term or
technique that is foreign to you at any time during the assembly of this kit,, please contact our staff with
any questions you may have.
IMPORTANT!
Please READ and RE-READ these build instructions, along with any other included documentation
before starting your build and/or contacting our staff for builder support.
Pre-Sanding
DO NOT SKIP THIS STEP. Before removing any parts from the laser-cut sheet wood, use a sanding
block loaded with 250 - 400 grit sandpaper, and lightly sand the back side of each wood sheet. This step
removes any residue produced as a result of the laser cutting process. We have found that most stock
wood sizes run several thousandths of an inch oversized. This step also slightly reduces the thickness of
each sheet of wood. Leave all parts in the sheet wood until required for assembly.
Protecting Your Work Surface
Use the poly tube (that this kit was shipped in), as a nonstick barrier between your work surface and the
product assembly.
Bonding the Assembly
This product’s tabs and notches interlock like a 3D puzzle. We strongly suggest that when fitting parts,
you “dry fit” (use no glue) the parts together first. It is advised to work 1 - 2 steps ahead in the
instructions, using this dry-fit technique. This allows the opportunity to inspect the fit and location of
assembled components, and shows the benefits of our construction technique. As each successive part
is added, it contributes to pulling the entire assembly square. Once you arrive at the end of a major
assembly sequence, square your work on a flat work surface, and bond the dry-fit joints with glue. Using
the dry-fit process, you’ll be able to recover from a minor build mistake, and will ultimately end up with a
square-and-true assembly.
Unless otherwise noted in the instructions, we find it easier to “tack glue” parts (temporarily bonding parts
in assemblies, using a small dot of glue). When using medium CA glue, apply with a fine-tip CA glue
applicator. Never bond painted or covered assemblies with thin CA, as it can destroy the finish of a
beautifully prepared model.
Never Force the Fit!
This is a precision laser-cut kit. Our lasers cut to within 5 thousandths of an inch in accuracy. Yet the
wood stock supplied to us by the mill may vary in thickness by up to 20 thousandths. This variance in the
wood stock can cause some tabs and notches to fit very tightly. With this in mind, consider lightly sanding
or lightly pinching a tight-fitting tab, rather than forcing the parts together. You will break fewer parts in
assembly, and end up with a square-and-true airframe.

Builder’s Notes
Build Instructions
1928 Pietenpol Sky Scout UM - Build Instructions © 2015 Stevens AeroModel, all rights reserved.!Page 7

Construction (continued)
Fuselage parts are designated with the letter “F” followed by a number. Parts have been numbered so
that the fuselage assembly follows a sequential order: F1 to F32.
Note: When initially bonding parts, use a single, small drop of medium CA glue, applied sparingly with a
CA glue applicator tip, to “tack glue” the part in place. Should you commit an error in assembly, it will be
easier to recover from the mistake and remove or correct the part in error, if you do not soak the assembly
with glue after each step! This method of assembly will allow our interlocking design to do its job.
As each successive part is installed within the fuselage, it will help pull the entire structure square and
true. When a major assembly is completed, revisit all joints and bond completely. Do not use excessive
amounts of glue, as this only adds weight to the model.
1. Central Crutch - Lay F1 (sheet 03/08, 1/20 in. balsa) on the work surface with the side
etched “bottom” facing up. Fit the nylon receiver clip to parts F2 and F3 (sheet 08/08, 1/32
in. ply). Fit the completed receiver tray to F1. Position the receiver clip with the long arm
toward the front of F1. Bond with CA.
2. Battery Tray - Lay F4a (sheet 08/08, 1/32 in. ply) on the work surface and press F4b
(sheet 08/08, 1/32 in. ply) into the slot and notch in F4a. Bond with CA.
3. Lay F4c (sheet 08/08, 1/32 in. ply) on the work surface with the side etched “front” facing
up. Fit the battery tray to the right side of F5c (marked with the letter “R”). Orient the battery
tray assembly with the arrows pointing forward/up. Bond with CA.
4. Apply a strip of self-adhesive velcro (PKZ1039), available from stevensaero.com to part
F4a.
5. Fit and “tack glue” completed F4 former and formers F5 and F6 (sheet 01/08, 1/20 in. balsa)
to the bottom of F1. Refer to Detail Sheet 1 of 2 for the proper location of each former.
6. Fuselage Sides - Fit and “tack glue” F7 (sheet 03/08, 1/20 in. balsa) to the right side of the
central crutch. Place F7 so that the etched side is facing in. Note: The front edge of part
F7 will align the center line of the side of former F5.
7. Fit and “tack glue” F8 (sheet 03/08, 1/20 in. balsa) to the left side of the central crutch.
Orient F8 so that the etched side is facing in.
Pro Builder Tip: We painted the areas on our display model, that would normally remain
the raw wood, in a color that matches our chosen color scheme.

and F10. F9 will rest in the front portion of the slots.
9. Fit F10 (sheet 08/08, 1/32 in. ply) immediately behind F9. Make sure both F9 and F10 are
fully seated, then glue with CA around the edges, to bond in place. Note: Ensure that no
glue enters the landing gear pocket.
10. Fit and bond the fuselage doublers, parts F11 (sheet 04/08, 1/20 in. balsa) to the inside of
the right and left fuselage sides, between formers F10 and F4. Place both F11s so that the
arrows on each are pointing forward.
11. Rear Fuselage - Fit and “tack glue” former F12 (sheet 03/08, 1/20 in. balsa) between the
rear fuselage sides. Ensure that the “Top” etching on F12 faces up.
12. Assemble the fuselage bottom F13 from parts F13a and F13b (sheet 03/08, 1/20 in. balsa).
Refer to the Fuselage Bottom Detail drawing on Detail Sheet 1 of 2. Fit and “tack glue” F13
to the bottom of the fuselage.
13. Turn the fuselage upright, and square it against the work surface. Ensure that the rear of
the fuselage sides are aligned with each other, and that they are vertical. Tape them
together at the rear, using low-tack masking tape. “Final bond” the fuselage with CA.
14. Fit and bond the notched formers F14, F15 (sheet 02/08, 1/20 in. balsa), and F16 (sheet
04/08, 1/20 in. balsa) to the notches in the top of the rear fuselage. Refer to Detail Sheet 1
of 2 for their proper location.
15. Fit the stringers, parts 1, 2, and 3 (sheet 04/08, 1/20 in balsa) to the notches in formers F6,
F14, F15, and F16. Stringer 1 will rest in the center notches: Stringer 2 will fit in the
notches on each side of stringer 1; Stringer 3 will fit in the notches on each side of stringer
2. Bond with CA.
16. Front Fuselage - Turn the fuselage upside down. Fit F17 (sheet 04/08, 1/20 in. balsa) to
the notches in the fuselage sides immediately behind the landing gear pocket, and to the

17. Fit and bond former F18 (sheet 02/08, 1/20 in. balsa) to the slots near the center of F1.
Fit and bond the strut doublers F19 into the notches in each side of F1, between formers F5
and F18. Make sure that the arrows on the F19s face forward.
18. Locate the nose sheeting, part F20 (sheet 02/08, 1/20 in. balsa). Lightly spray the etched
side of F20 with glass cleaner and allow it to soak for a minute or two. Fit F20 (wet side
out) to the tabs at the top of formers F5 and F8. Wrap it over the formers until it comes into
contact with the fuselage sides. Take care when handling the corners of F20 (as they can
easily break off) until taped in place. Using low-tack masking tape, secure F20 to the
fuselage. Allow it to completely dry. When dry, remove the tape and bond F20 to the
fuselage with CA.
19. Motor Mount - Lay F21 (sheet 08/08, 1/32 in. ply) on the work surface, with the etched
“Top” side facing up. Fit the two F22s (sheet 08/08, 1/32 in. ply) to the rear slots in F21.
Note: That the front of parts F22 will not contact F21. This gap allows the mounting
tabs (on the motor) to slide under parts F22. Bond with CA.
20. Fit and bond F23 (sheet 08/08, 1/32 in. ply) to the long tabs at the front of each F22.
21. Turn the assembly upside down. Fit and bond two F24s (sheet 08/08, 1/32 in. ply) to the
front slots in F21.
Pro Builder Tip: To ensure a perfect fit, always remove and sand smooth the attachment
points/nubs on the laser-cut plywood parts.
22. Fit the completed motor mount assembly to the front of former F5, and bond with CA.
23. Engine Cowling - Turn the fuselage upside down. Fit part F25 (sheet 07/08, 1/8 in. balsa)
to the tabs at the bottom of each F24. Bond with CA.

25. Cowl - Fit and bond one part F27 (sheet 01/08, 1/20 in. balsa) to each side of the motor
mount assembly. Engage the tabs on the sides of former F5. Align F27 against the sides
of F26. Ensure that the notches at the front of F27 align with the base of F26.
26. Fit and bond F28 (sheet 07/08, 1/8 in. balsa) to the tabs on the top of each F22 of the motor
mount. Place F28 with the etched side facing up. Align F29 (sheet 07/08, 1/8 in. balsa)
within the etched lines on F28, and bond in place. Repeat this process, to install parts F30,
F31 (sheet 07/08, 1/8 in. balsa), and F32 (sheet 02/08, 1/20 in. balsa).
27. Sanding - Lightly sand the fuselage, removing excess glue and smoothing the joints
between parts. Sand the cowl laminations to match the contours of formers F5 and F24.
Sand and taper F25 from the front to the back, flush with the bottom of former F5. Round
the bottom edges of F27 to flow into F25. Sand F26 to match the profile shown on Detail
Sheet 1 of 2.
Wings
Wing parts are designated with the letter “W” followed by a number. Parts have been numbered so that
the wing assembly follows a sequential order: W1 to W8.
28. Wing Center Section - Fit ribs W2 and W3 (sheet 04/08, 1/20 in. balsa) to spar W1 (sheet
08/08, 1/32 in. ply). Ensure that ribs W2 are inside of ribs W3.
29. Fit the rear of the wing center section part W4 (sheet 01/08, 1/20 in. balsa) to the tabs at the
rear of ribs W2. Note: Bond at the rear tabs only.
30. Wrap W4 over the top of ribs W2. Engage the tabs at the center and front of the ribs, and to
the tab at the center of the spar W1. Hold the wing center section on a flat surface. Then
bond W4 along the full length of ribs W2.
31. Right Wing - Lay W5R (sheet 01/08, 1/20 in. balsa) on the work surface, with the etched
side facing up. Fit the tabs at the rear of ribs W6, W7, and W8 (sheet 04/08, 1/20 in. balsa)
to the slots at the rear of the wing panel. Refer to Detail Sheet 2 of 2 for the correct
placement of the ribs. Bond the rear of the ribs to W5R with CA.
32. Turn the wing panel over, and wrap the wing panel over the top of the ribs. Fit each rib into
notches along the front edge of the opening in the wing panel. Bond the ribs to the leading
edge of the wing, and at the notches and spar locations. Pick up the panel and examine
each rib, closing any gaps between the ribs and the wing panel. Bond with CA.
Repeat steps 31 and 32, to build the left wing panel. Start with W5L on the work surface,
with the etched side facing up.

Construction (continued)
Radiator
33. If desired, pre-paint the radiator parts before assembly. We painted the front and back of
the radiator body R1 (located with your cut wood parts) flat black. We painted the front and
rear radiator parts R2 and R3 (sheet 08/08, 1/32 in. ply) gold. The radiator cap R4 (sheet
04/08, 1/20 in. balsa) was painted to match our color scheme, and the filler stem R5 (sheet
04/08, 1/20 in. balsa) was painted gold. Refer to the radiator detail for part locations. Align
R2 over the front (etched) side of R1 and bond with CA. Align R3 over the back of R1 and
bond. Bond R5 within the etched circle on R4. Then bond R5 to the center of the radiator
top. After the radiator was assembled, we painted the top and sides gold.
34. Cut one of the 1/16 in. x 1/4 in. aluminum tubes (located in the hardware bag) in half. Apply
a small drop of CA to the end of the tube. Press one half of the aluminum tube into the hole
in the front of the radiator, part R2.
Tail Surfaces
35. (Step not shown) Locate the vertical stabilizer part V and the horizontal stabilizer, part H
(sheet 05/08, 1/20 in. balsa). Sand smooth, and remove the residue from the laser cutting
process. Sand the leading edges and tips round. Leave the trailing edges square.
36. Assemble the elevator from parts E1 (sheet 08/08, 1/32 in. ply) and two E2s (sheet 05/08,
1/20 in. balsa). Bond with CA.
37. Align the leading edge of the elevator assembly with the edge of the work surface, and sand
a 45-degree bevel along the entire leading edge. This bevelled side will now be referred to
as the “bottom” of the elevator. Sand both sides of the elevator smooth, and remove any
laser cutting residue. Leave the trailing edges square.
38. Locate the rudder, part R1 (sheet 05/08, 1/20 in. balsa). Lay it on the work surface with the
left side facing up. Align the leading edge of the rudder with the edge of the work surface,
and sand a 45-degree bevel along the entire left side of the leading edge. Sand both sides
of the rudder smooth, and remove any laser cutting residue. Leave the trailing edge
square.
Struts
39. Cabane Struts - Assemble the cabane struts from parts CS1, CS2, and CS3 (sheet 08/08,
1/32 in. ply) over Cabane Strut Detail drawing on Detail Sheet 1 of 2. Orient parts CS2 and
CS3, so the arrows on each part point toward the front of the assembly. Bond with CA.
Make two sets of struts.
40. Landing Gear Struts - Assemble the landing gear struts from parts LG1 and LG2 (sheet
08/08, 1/32 in. ply). Bond with CA. Make two sets of landing gear struts.
Wheels
41. If using the wheels supplied in the kit, this step may be skipped. If using the optional
1-1/2 in. wheels (DUB-150ML), bond one wheel cover W (sheet 06/08, 1/16 in. balsa)
to each side of the wheels. Sand the wheel covers to a streamlined shape.

Push Rods and Receiver
6. Refer to the Push Rod Detail drawing on the Detail Sheet 2 of 2. Make a “snake” bend at
one end of each of the .015 in. wires supplied in the kit.
7. Connect the “snake” bends to the servo tabs on the receiver brick. Note: The holes on the
servo tabs are different sizes. Insert the pushrods into the middle hole of the servo tabs.
8. Refer to the Push Rod Detail drawing on Detail Sheet 2 of 2. Feed the push rods through
the fuselage and out through the exit slots in the fuselage sides. Fit the receiver brick to the
receiver tray by first slipping the rear of the circuit board into the notch in the short arm of
the clip. Press down on the front of the circuit board until it snaps under the long arm of the
receiver clip.
9. Cover the bottom of the fuselage.
